>Description:

I'd like to commit the following patch to HEAD and MFC to 10 which
enables the --sysroot=/foo option to ld.  This will allow the
installed linker to be used in cross compilation.  It should just
work, but it's quite possible that ports exist that probe for
--sysroot in their configure script and will break as a result.
